To all whom it may concern.:

Be it known that I, WILLIAM PHENIX, of Chicago, county of Cook, andState of Illinois, have invented certain new and useful Improvements inMeans for Carrying Gables Around Curves, of which the following is afull, clear, and exact description, that will enable others to make anduse the same, reference being had to the accompanying drawings, forminga part of this specification. A

The object of this invention is to provide an improved means forcarrying traction-cables operating street-cars around curves; and itconsists of certain novel features in the construction, combination, andarrangement of devices, as will be hereinafter set forth.

Figure l is an end elevation of the cableconduit embodying my improvedfeatures; Fig. 2, a plan ofa curved section of the roadway; Fig. 3, avertical section of a double sheave; Fig. 4, a plan of two of thepulleys and means for supporting the same between the conduityokes; Fig.5, a view of the under side ofthe same, and Fig. 6 an edge view of oneof the bars supporting the double sheaves, Fig. 7, a detached detail.

Referring to the drawings, A represents the conduit-cable passage; A',the yoke; A2, asupporting plate-iiange riveted to said yoke, the outertop edges of which supportthe track-rails. The double sheave-wheelconsists of the upper sheave, B, and the lower sheave, B', both looselymounted on the vertical stationary shaft B2. The upper square end ofthis shaft is secured and retained in place by being inserted in anaperture formed in the junction of the two arms C C'. rlhe outer end ofthe arm C is bent upward and bolted to one of the Z-slot irons B3, asshown in Figs. land 4. The corresponding arm,0, extends off at rightangles, and is bolted to the yoke-flange A2. The lower square end ofthe. shaft B2 is inserted in the socket-bearings G2, formed on the baror bars D, supporting the sheaves between the conduit-yokes. Thebearings C2 are of a truncated-cone shape, as shown in different iiguresof the drawings. The lower part of the shaft B2 is of a greater diameterthan the upper part, thus forming the central shoul- (No model.)

der, a, on which rests the under side of the stationary collar a',separating the hubs of the two sheaves. The upper end of thehub of thesheave B is cupped out, so as to receive a lubricant, the lower endbeing provided with a shallow recess, which projects down a little Wayover the upper side ofthe collar a. The under side of this collar isalso recessed, the annular flaring edge e2 extending down over the upperbeveled end of the hub of the lower sheave, B', as shown in Fig. 3.Thelower end of the hub of the sheave B is likewlse recessed, and isprovided with the annular iiaring rim a", which corresponds to thecontour of the socket-bearing C2. By this arrange ment the sheavesareretained in proper relative position andindependent ofeach other,andthe dirt and grit prevented from getting into the bearings. The lowersheave, B', is provided with a wide face, a4, extending upward from thecable-groove, which is located in the extremelower part of thesheave-whcel, as shown in Fig. 3. rlhis wide surface on the lower sheaveprovides a ridingsurface for the outside cable when not in cont-act withthe gripsheave dias this cable should have some play in orderto relievethe same ofany undue strain. These two sheaves are adapted to rotate ina horizont-al plane and independent of each other, and are intended tobe rotated in opposite directions by the frictional contact of the twoparts of au endless cable having a corresponding movement.

Fig. l shows the relative position of the sheaves to the movingcable-grip D', and Fig. 2 the arrangement of the series oi sheaves toease the cable around a curve. rlhe ends of the bar D are supported byand bolted to the angle-brackets b, which are in turn riveted to theyoke-ange, as shown in Figs. land 6. The brackets b are provided withthe elongated aperture b, through which the bolts b2 are inserted, bywhich arrangement the bars D are adapted to have a lateral adjustment,so as to bring the series of sheave-wheels into a true alignmentrelative to each other. rlhe adjustable keys d are inserted between tlieends of the bar or bars D andthe yoke-iiange, and serve the purpose ofstitl'ening the structnre and relieving the bolts b2 of undue strain,and readily permit of the barsbeing removed at any time by driving outthe keys and takving out the holding-bolts, which could not be done werethey made long enough to bear against each yoke-flange, on account ofthe endwise strain. v

The cable-carrying sheaves may be removed singly at any time forrepairs, and readily replaced without having to stop the cable, bysimply taking out the bolts and removing the arms C C.

d diarethe cable-carrying sheaves attached to the' car-grip, and d3 thecable, which remains in the sheave d and runs in the horizontal sheaveB, both back of and in advance of the grip when rounding a curve. 'Iwosets of the sheaves B B are arranged in the space between each of theyoke-flanges, as shown in Fig. 2, the radial dotted lines representingthe position of the yoke-anges. By this arrangement the friction andwear on the cable is reduced to a minimum, and repairs on the.

means employed for carrying cables Iaround curves greatly facilitated.

Having thus described my invention,w.hat I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with a traction-cable, of a system or series ofsheave-wheels rotating in a horizontal plane and arrangedin pairs on thesame shaft, the single companion sheave of each pair being adapted torotate in opposite directions, substantially as and for the purpose setforth. i

2. The combination, with the yoke-flanges,

ofthe bar D, provided with the socket-bearings Gl, and the meansdescribed for adjustably securing and retaining said bar in rela.- tionto said yoke-flanges, substantially as and for the purpose set forth.

3. The combination, with the bar D, provided with the socket-bearingsG2, of the ver-.

tical stationary shaft B2 and the companion arms C C', whereby saidshaft is ,retained in to rotate independent of each other, substan-Itially as and for the purpose set forth.

5. The combination, with the stationary shaft B", of the collar a',lhaving the under side recessed and provided with the daring edge a2,andthe lower sheave-wheel, B', having part of the hub beveled andfitting inside of said iiaring' edge, substantially'as and for thepurpose set forth.

6. The eombinatiomwith the wheel B, having the wide face a* and providedon the lower end of the hub with the annular flaring rim a?, of thesocket-bearing C2, having a beveled contour, substantially as and forthe purpose set forth;
